SPECIFICATION forming part of Letters Patent No. 583,360, dated May 25, 1897.

Application filed November 16,- 1896. Serial No. 612,321. (No model.)

To all whom it may concern;

Be it known that I, PHILIP T. DODGE, of New York, county of New York, and State of New York, have invented a new and useful Improvementin Linotype-Machines, of which the following is a specification.

In linotype-machines-such, for example, as that represented in Letters Patent of the United States, No. 436,532, granted to Ottmar 1o l\[ergenthalerSeptember16,1890-type-metal slugs or linotypes are cast in a mold against character matrices an d spaces, which are temporarily composed in line and presented across the open face of the mold. The spaces employed are of the expanding pattern to effect justification of the line, and consist each of two wedges connected by a sliding joint, the shorter wedge being held fast in the line, while the longer wedge is thrust through In practice it is found that foreign matters occasionally lodge on the side faces of the matrices and the spaces, the result being that the matrices are held apart during the casting operation,

so that molten metal flows between them.

The objectof my invention is to provide for the automatic cleaning of the side faces of the matrices without change in the machine; and to this end it consists, essentially, in providing the machine with double-wedge spaces, some of which have their short stationary wedges or members orf' the right-hand side, while others have them on the left-hand side.

\Vhen the spaces are reversely arranged in 3 5 this manner, the long wedges or part of them will during justification move in contact with the left-hand side of the adjacent matrices, while the long members of the other spaces will in like manner he moved in contact with the right-hand side of the adjacent matrices, the effect in each case being that the space removes and carries away from the surfaceof the matrix any dust, gum, or foreign matters which may have lodged there- 5 on. Owing to the fact that the number of spaces differ in successive lines and that the words vary in length each matrix will in the regular course of operation be cleaned on both surfaces by the spaces. The movable parts of the spaces may be made flat and smooth on their outer faces, or serrated, roughened, or

perforated in order to adapt them the better for the cleaning action.

Figure 1 is a front elevation of the principal parts of the lllergenthaler machine; Fig. 2, a view showing the manner in which the usual spaces are inserted in the line of matrices. Fig. 3 is a front view, 011 an enlarged scale, showing two cleaning-spaces inserted in reverse positions in accordance with my invention. Fig. 4 is a perspective view of one of the spaces such as I employ. I

Referring to Fig. 1, A represents the magazine in which the matrices are stored and from which they may be delivered one at a time by connections from a keyboard B to an inclined belt 0, on which they descend into the assembler D; E, a magazine for the wedge spaces, from which they are delivered one at a time through finger-key connections into the assembler to take their places between the matrices as composition progresses.

From the assembler the composed line is transferred laterally to the vertically-moving elevator F, by which it is first lowered to the casting mechanism G and afterward raised for transference to the second elevator II, which in turn lifts it to the distributing mechanism I, which restores the matrices to the magazine, while the spaces are transferred directly to their magazine E.

The foregoing parts may all be constructed and arranged to operate in the ordinary man- The spaces, instead of being inserted as usual with all their stationary wedges on the same side, are arranged part of them with the short wedge on the right-hand side and the remainder with the short wedge on the lefthand side, as clearly represented in Fig. Then the spaces are thus arranged in the matrix-lin e, confined as usual between clamping-jaws, as in Fig. 2, and the long wedges pushed upward through the line to effect j ustification as usual, each of the moving wedges will rub against and clean the surface of the 5 adjacent matrix, the matrices being cleaned on the right-hand side by spaces having the long wedge at the left and cleaned at the left side by spaces having the long wedge on the right. I prefer to provide the wedge with 10:) serrations, as shown in Figs. 3 and 4, or with depressions in any other form. These must of course be of such form and so located that they will not permit the molten metal to enter between the matrices at the casting-{Join t. If they are at the upper end of the wedges, they will be carried above the casting-point by the justifying movement before casting occurs.

I am aware that an expansible space has been constructed in the form of an intermediate wedge and two outside wedges, both of which are moved through the line in contact with the matrices, but they were not intended for cleaning purposes. In practice they were found inoperative and are now out of use in the art.

Having thus described my invention, what I claim is- 1. I11 a 1inotype-machine, and in combina tion with a series of matrices, a series of spaces each consisting of a short wedge held in the line and a long wedge movable therethrough,

said spaces being arranged part of them with the stationary wedge on the right and others with the stationary wedge on the left,whereby the cleaning of both sides of the matrices is automatically eflfected.

2. In a linotype-machine adapted to circulate the matrices and spaces, a series of double-wedge spaces part of them having the station ary wedge on the right and the remainder having such wedge on the left.

In a linotype-machine a double or com pound wed ge-space having the movable member provided with serrations or depressions to effect the cleaning of the adjacent matrix.

In testimony whereof I hereunto set my hand, this 20th day of October, 1896, in the presence of two attesting witnesses.

PHILIP T. DODGE.
